Known individually and collectively since the 1960s, Les Lalanne developed a style that defines inventive, poetic and surrealist sculpture. Having rediscovered the Renaissance art of casting forms from life, then employing contemporary electro-plating techniques, Claude Lalanne achieves a delicacy and sensitivity in her work unparalleled in cast bronze. François-Xavier Lalanne similarly found inspiration for his works in nature. In his words, "The animal world constitutes the richest and most varied forms on the planet." His subjects consist of a menagerie of animals, stylized forms oftentimes married with functionality. His works achieve streamlined elegance in their profound simplicity.

Most recently, Les Lalanne were the subject of a major retrospective at Les Arts Decoratifs in Paris and a large-scale public exhibition at the Fairchild Tropical Botanic Garden in Coral Gables, Florida. Their work was also featured on New York’s Park Avenue and Getty Station, and in the sale of the collection of Yves Saint Laurent. Their work is included in major collections including the Cooper Hewitt Museum in New York, the Museé Nationale d’Art Moderne/Centre Georges Pompidou, the Museé d’Histoire Naturelle in Paris, the City of Paris, the City of Santa Monica, and the City of Jerusalem.
